It is hoped 5,700 pupils aged 14 and over will spend up to four hours a week on the subject in a five-year pilot.
Classroom and online teaching, "real-world challenges" and work experience will be made available from September.
A Commons committee last week warned that a skills shortage was undermining confidence in the UK's cyber defences.
The risk that criminals or foreign powers might hack into critical UK computer systems is now ranked as one of the top four threats to national security.
Russia in particular is suspected of planning sustained attacks on Western targets.
Cyber security is a fast-growing industry, employing 58,000 experts, the government says, but the Public Accounts Committee has warned it is proving difficult to recruit people with the right skills.
UK's cyber security defences questioned
Russian hacks 'aim to destabilise the West'
The Department for Culture, Media and Sport is providing Â£20m for the lessons, which will be designed to fit around pupils' current courses and exams.
Digital and Culture Minister Matt Hancock said: "This forward-thinking programme will see thousands of the best and brightest young minds given the opportunity to learn cutting-edge cyber security skills alongside their secondary school studies.
"We are determined to prepare Britain for the challenges it faces now and in the future and these extra-curricular clubs will help identify and inspire future talent."
The government is already providing university funding and work placements for promising students.
An apprenticeship scheme has also begun to support key employers to train and recruit young people aged 16 or over who have a "natural flair for problem-solving" and are "passionate about technology".
Steve Elder, 20, who is a cyber security apprentice with BT, told BBC Radio 5 Live that educating young people about the risks and vulnerabilities of the cyber security world would help the UK prepare for the future.
He added: "Getting young people involved and getting them taught from a young age will allow them - even in their home environment - to protect themselves, before it has to come to people at a specialist level."
Mr Hancock told the BBC he wanted to ensure the UK "had the pipeline of talent" it would need.
Cyber security expert Brian Lord, a former deputy director at GCHQ, told BBC Breakfast that the scheme was an "essential initiative" to recruit more people into the profession.
He added: "There is perception that cyber security is all about techno geeks who have long hair, glasses, wear heavy metal t-shirts and drink red bull.
"There are those, and they do an extraordinarily good job. But there is a whole range of other activities... that can appeal to a wide cross section of children, graduates and apprentices, and at the moment they don't know what [is on] offer.
"The more exposure [children] can get [the more it will] prepare them for a future career and, as that generation needs to understand how to be safe online, you get a double benefit."
Schoolchildren in England will be offered lessons in cyber security in a bid to find the experts of the future to defend the UK from attacks.

Atletico led 2-0 from the first leg and Torres stunned the Bernabeu, smashing in left-footed after 49 seconds.
Sergio Ramos's header levelled but, in the first minute of the second half, Torres beat Pepe to slide in a second.
Real needed three goals to win after Cristiano Ronaldo's header but Atleti will meet Barcelona in the last eight.
Barca cruised to a 9-0 aggregate win over Elche, but for Atleti, the last-16 stage provided a stiffer test and significant bragging rights.
The La Liga champions inflicted a first domestic cup defeat on Carlo Ancelotti since he arrived to manage their city rivals in 2013.
Los Rojiblancos can also boast being five games unbeaten against Real this season, a record which looked certain to continue after less than a minute's play in the Spanish capital.
Soon after Ronaldo stopped parading his Fifa Ballon d'Or award moments before kick-off, Torres plundered the opener, sweeping into the top corner from 10 yards with a first-time shot following Antoine Griezmann's cross.
Torres, who left Atleti in 2007, had never scored at the Bernabeu with his boyhood club but, in for the unwell Mario Mandzukic, he left Real needing four goals to progress.
Ramos netted a last-minute leveller which spurred Real on to a 4-1 extra-time win over Atletico in last season's Champions League final and he was in the right place when goalkeeper Jan Oblak - making just his fifth appearance - flapped at a set-piece delivery.

Swarms of white shirts peppered the visitors' area and Ronaldo's goal-bound strike was only kept out by Mario Suarez on the goal-line as Real dominated with 76% of possession in the opening half.
But Diego Simeone's side only had 27% of the ball in the first leg and they again demonstrated the resilience he has instilled in them since taking over in December 2011.
The Argentine has delivered successive league finishes of fifth, third and first along with Europa League success in 2012 and a Copa del Rey triumph in 2013.
In Europa League, Champions League and Copa del Rey fixtures, he now has 16 successes from 18 two-legged ties and Torres's second came at the perfect time, killing Real's second-half hope.
He again collected a Griezmann pass before wrong-footing Pepe to fire under home keeper Keylor Navas.
Ronaldo - voted the greatest player in Portugal's history on Wednesday - headed in from six yards to reduce the arrears on 54 minutes before Torres was substituted to jeers from the home fans.
Karim Benzema could not turn their frustration to hope when he fired over from four yards as La Liga leaders Real relinquished their hold on Spain's coveted domestic cup.
Fernando Torres struck his first goals since returning to Atletico Madrid, firing a brace in a 4-2 Copa del Rey aggregate win over holders Real Madrid.

After all, it was unusual for a prime minister to use the bully pulpit in India to exhort people to end this appalling practice and build more toilets.
A staggering 70% of Indians living in villages - or some 550 million people - defecate in the open. Even 13% of urban households  do so. Open defecation continues to be high despite decades of sustained economic growth - and despite the obvious and glaring health hazards.
The situation is so bad that open defecation is more common in India than in that are poorer countries such as Bangladesh, Kenya, Democratic Republic of Congo, Malawi, Burundi and Rwanda.
But building toilets may not be enough to end open defecation in India, a new study has found.
A team of researchers asked people in 3,235 rural households in five north Indian states where they defecate and their attitudes to it.
Some 40% of Indians live in these states - Bihar, Madhya Pradesh, Rajasthan, Haryana and Uttar Pradesh. They also account for 45% of households without a toilet. Also, a third of all people worldwide who defecate in the open live in these five states.
The study found that people in households with working toilets continue to defecate in the open, and that toilets provided by the state are especially unlikely to be used.
"In short," the study says, "we find that many people have a revealed preference for open defecating such that merely providing latrine access without promoting latrine use is unlikely to importantly reduce open defecation."
The study found open defecation is very common, even in households with toilets. Toilet use did not necessarily increase with prosperity: in Haryana, one of India's richest states, most people in the villages continue to defecate in the open. Also, men living in households with toilets are more likely to defecate in the open than women.
Why do so many Indians still prefer not to use toilets, even if they are available?
The survey found a range of replies - most said they found it "pleasurable, comfortable, or convenient". Others said it "provides them an opportunity to take a morning walk, see their fields and take in the fresh air". Still others regarded open defecation as "part of a wholesome, healthy virtuous life".
"Building toilets is not enough. What you need is a widespread motivation and information campaign," says Dr Bindeshwar Pathak of Sulabh, a non-profit organisation which has built 1.3 million household toilets in villages.
MP and writer Shashi Tharoor says Indians also have a cultural problem  when it comes to sanitation: "We are a nation full of people who live in immaculate homes where we bathe twice a day, but think nothing of littering public spaces, spitting on walls, dumping garbage in the open and urinating and defecating in public, because those spaces are not 'ours'."
So how do you promote behavioural and cultural change?
India, researchers say, "needs a massive campaign to change sanitation preferences" and promote toilets by linking sanitation behaviour with health. One of the ways it can be done is by raising an army of sanitation workers and campaigners in the villages to spread the message.
Punishment can also help, within reason: In a part of Haryana where Sulabh has built 100 household toilets a village council chief fines people caught defecating in the open.
Imaginative designs could also help: Sulabh has designed an open roof toilet to incentivise men who feel claustrophobic in the confines of a toilet, although it is not clear how this will work in bitter winters or monsoons.
Women could possibly be persuaded to help with education efforts - studies show that they are likely to use toilets more than the men.
"I know of women in villages who stay up all night to take their daughters to defecate outside," says Dr Pathak.
Mr Modi has announced plans to build more than 100 million toilets in the country to end a shameful practice. But many believe the money will not be well spent unless it's accompanied by a massive awareness campaign, involving the government, non-profit groups and citizens.

When Prime Minister Narendra Modi, in his  Independence Day speech, vowed to eliminate open defecation, India  took notice.
